To all whom it may concern.

Be it known that we, OLIVER J. Mensrrrcn and Enwin L. Cnosnr, citizens of the United States, residing at Detroit, county of Wayne,

State of Michigan, have invented a certain new and useful Improvement in Pouring Mechanism for Refractory Furnaces, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, referments within its base line, in a way to make possible the practically continuous 'qouring into molds located at the same distance from the furnace drum, since with our improved where the molds are placed, with the drum as a whole moved about it. I

In the drawings:

Figure 1 is an end elevation of our improved apparatus.

Figure 2 is a side elevational view, showing the relation of the pouring spout to the bar removably attached at one side of the drum when pouring is to begin. 7

Figure 3 isa side elevational view of the drum end of one of the hoisting members.

Figure 4 is an end elevation of a modified form of apparatus, in which the lifting of one side of the drum is done from above rather than from beneath, as by means of the jack shown in Figure l.

A represents the rockable refractory lined drum, providedwith a filling door B and a pouring spout hole-C. Arranged about the periphery of the drum within each edge thereof are encircling metal bands composed of the trackway portion E and tooth portion F, adapted to rest upon the supporting rollers D and D and to be rotatably actuated by the gear G. Ordinarily the furnace drum is not rocked back and forth so that the pouring spout is much below the position shown in Figure 1, although it may be movedto a position directly beneaththe central axis of the drum, as for emptying and cleaning out of the melting chamber. With a furnace constructed to oscillate thus, there is a'relatively small space, within the line of the furnace drum, in which a mold can be rested when the metal is ready for pouring, since such space as there is is largely occupied by the supporting rollers and other operative elements. Furthermore, after each mold is filled and further pouring from the spout Cv is halted by slight rocking of the 'drum in the reverse direction (to theright as shown in Figure 1), in order to permit the removal of the filled mold and the substitution of another therefor, the quantity of fluid metal within the drum being thus diminished, for pouring into subsequently placed molds, the furnace drum would have to be rocked further around to a position where the pouring spout is lower than before and consequently further than ever within the line offthe drum.- 1 3 To obviate this difiiculty, we place oneach end ofthe furnace drum, in approximately the same peripheral position as the pouring spout C, a bracket or projecting arm 0,

through the'perforated ends of whichabar J is thrust when the drum has been nearly frames K which are locatednear the ends of the furnace drum. From a position peripherally distant from the pouring spout from one-third-to one-, half of the periphery of the drum, and located intermediate the encircling metal trackways near each edge, 18 a-projecting rotated to pouring position. A slight furstrut L, from which laterally extends a trunnion stud M which is adapted to rest in the troughed or recessed upper end N of the hoisting jack P, which engages in the com plementarily threadedblock Q, the teeth of whose gear are adapted to be engaged by those of a complementary gear S mounted on the shaft of the actuating motor T.

With the'ba-r J restingfirmly in the top of the frame K, the lifting of the jack P begins under actuation from the 'motor' T,

thus serving to lift the entire drum A from its position upon the right hand air of supporting rollers D (as shown in Figure 1) and elevating it to the dotted line position shown in Figure 1. The path of the trunnion M, on theright hand side of the drum, not being a truly vertical one, but rather following the arc of a circle Whose center is the bar J, provision is made whereby the trunnion U enables the jack]? to ifolloxv the slightly curved'course indicated'by the dotted line (1)) Without displacement of its connected parts.

\Vith .the drum A in the dotted line'pos-ition shown, the horizontal top level of the molten metal Within the drum A is now 10W- ered to the level of the dotted line (a);

The pouringispout is thus-lei'tin a position sufficiently far out from the supporting roll-- crs bencaththedrumfil, so that a continuous succession of (molds may be moved into receivingposition, relatively thereto, as by means of a turnable table about Whose outer edge tl1eemptymolds are spacedly arranged, 'or by'means of ail-endless belt or traveling platform ;I,:running;along'the floor just beneath the pouring position ot'the spout C. After pouring, the drum is loivered'by a reversal of the direction of rotation 01" the gear R' and "its associated parts, until the drum rests once more upon the rollers D and D.

Inthemodiliedfform shown in Figure 3, there is substituted for the upwardly acting ,jack'P, the tackle 'V suspended from the pul ley W, and actuated for raising and'lower- 'ing; by means of the 'motorX or equivalent 1 hoisting means, the pulley 7 being sup- .pi'orted from the 'over engaging frame Y.

This latter'may be also made'to serve as the :supportfor a .traclrZ, along which a. car

Z of material mayberun-until it'is in position for dumping into the upturned filling opening B in the drum A. The same princi- Jple applies 'asto the bar J being the rotative center, about which the body of the drum is 'liftechas is the lcaseuvhen the jack shown in Figure 1 is relied upon.

-Wh-atvve claim is: 1.111 combination with a rotatable turna'cedrum, meansonone side thereof adapt cdto cooperate with. a removable external supportlng member in constituting a'laterally disposed turning axis, and means for lifting upon the opposite side of the drum,

whereby the elevation thereof is through an arc Whose center is located coaxially with s-ald turning axis.

2. The combination, with a rockable furnace drum, of meansadapted to be detachably correlated with one side of said drum adjacent the line of the pouring orifice whereby the drum is temporarily supported against furtherrotative movement, and elevating meansadapted to act upon the opposite side of the drum from said detachof its pouring orifice, and means for elevating the opposite side of the drum about its line of contact with said external support as a center, thereby placing the pouring orifice in a more favorable pouring position.

a. In combination With a rotatable furnace drum, removable means for supporting that side thereof wherein the'pouring orifice is located When in pouring position, means for elevating the drum about the linen-f support as a turning center, and means for successsively presenting a plurality of molds for filling from the pouring spout as thus located.

5. In combination With a rockable furnace drum, means for temporarily supporting that portion of the drum Wherein'the pouring spout is located When in pouring position, and means for elevating the opposite side of the drum about the line of contact with said temporary supporting means as a center.

6. The combination, With a rockable furnace drum, of means for temporarily supporting against further rotative movement a selected peripheral point adjacent the pouring spout oi the drum, and means adapted to act upon a peripherally distant portion of the drum, to raise the same'about said holding point as a center.

7. in a rotatable metal treating furnace,

in combination with a'rotatable'drum, removable supporting means adapted to be placed inoperative relation to said drum adjacent the pouring orifice therein, and means adapted to act upon a peripherally remote portion of the drum from thatengaged by said supporting members, Wherebythe same may be elevated to pouring position through anarc Whose axial center is coincident With the line of contact of said drum andsaid removable supporting members.

In testimony whereof, We,-OLIvER MAR- SHICK and EDWiNL. GROSBY'Sl'gn thisspecilication in the presence oftwo witnesses. OLIVER; J. QMALRS'HICK. EDWIN L. CROSBY.
